These designations spell out the number of contacts and how they behave during operation. For instance, a basic on/off light switch is an example of a single-pole (i.e., one-circuit) single-throw (i.e ...

Using eight digital inputs, this circuit simplifies decoding of the common membrane 4x4 keypad matrix and eliminates the traditional requirement of scanning rows or columns. Any X-Y switch matrix, ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader ...

Designers can make useful products that include electrical components close electrical componentA device in an electric circuit, such as a battery, switch or lamp.. They allow a product to have lights ...
